Calnetix Technologies based in the U.S. will introduce a new system called the Hydrocurrent that produces power for the ship’s electric load from heat recovered out of the engine’s jacket water up to 125kW. The system is claimed to offer short payback times and it pays for itself in a very short time by reducing the load on the ship’s bunker-fueled generators. This can translate into fuel savings of up to 200 tons per year. Organic Rankine cycle (ORC) heat recovery technology is used along with Calnetix’s Thermapower and Carefree integrated power module to convert thermal energy into mechanical power. The system can pull usable heat from a source with temperatures as low as 80°C where other heat recovery systems require much higher temperatures.
